Chefspec与Hashicorp Vault

Question

我正在尝试使用ChefSpec来测试Chef和Hashicorp Vault的实现

食谱

chef_gem 'vault' do
  compile_time true if Chef::Resource::ChefGem.instance_methods(false).include?(:compile_time)
end

require 'vault'

Vault.address = 'https://address:8200'
Vault.token = citadel['foo/bar']
Vault.auth_token.renew_self

测试

require_relative '../spec_helper'

describe 'wrapper::default' do
  context 'role is foo' do
    let(:chef_run) do
      ChefSpec::SoloRunner.new(platform: 'ubuntu', version: '14.04') do |node|
        node.default['role'] = 'foo'
        const_set(:Vault, Module.new)
      end.converge(described_recipe)
    end

    before(:each) do
      allow_any_instance_of(Chef::Recipe).to receive(:require).and_call_original
      allow_any_instance_of(Chef::Recipe).to receive(:require).with('vault').and_return(true)
      allow_any_instance_of(::Vault).to receive(:address).and_call_original
      allow_any_instance_of(::Vault).to receive(:address).with('https://localhost:8200').and_return(true)
    end

    it 'install vault gem' do
      expect(chef_run).to install_chef_gem('vault')
    end
  end
end

错误

Failure/Error: expect(Chef::Recipe::Vault).to receive(:address).and_call_original

     NameError:
       uninitialized constant Vault

如何存根Vault变量？这是Hashicorp Vault不是chef-vault

Answer 1

我来到这里，仍然不能弄明白它，所以我最终将我的存储库代码移动到我自己的库中，我将它包含在菜谱中，所以我不能在ChefSpec运行时模拟它。

所以我在my-cookbook/libraries/my_vault.rb下使用了下面的代码：

require 'vault'

module MyVault
  module Helpers
    def get_vault_secret(secret)
      Vault.configure do |config|
        config.address = "#{node[:vault_url]}"
        config.token = "#{node[:vault_token]}"
      end
      Vault.logical.read(secret)
    end
  end
end

在我的食谱里：

Chef::Recipe.send(:include, MyVault::Helpers)

creds = get_vault_secret("secret/jmx")
user = creds.data[:user]
password = creds.data[:password]


template "/etc/app/jmx.password" do
  source "jmx.password.erb"
  mode 0600
  owner "dev"
  group "dev"
  variables({
                :user => user,
                :password => password
            })
end

还有我的规格测试：

require 'chefspec'
require 'chefspec/berkshelf'

describe 'app::metrics' do
  platform 'ubuntu', '14.04'

  before do
    response = Object.new
    allow(response).to receive_messages(:data => {
        :user => "benzi",
        :password => "benzi"
    })
    allow_any_instance_of(Chef::Recipe).to receive(:get_vault_secret).and_return(response)
  end


  describe 'adds jmx.access to app folder' do
    it { is_expected.to create_template('/etc/app/jmx.access')
        .with(
            user: 'dev',
            group: 'dev',
            mode: 0644
        ) }
  end

我已经回复了你的电子邮件，你想要allow_any_instance_of(::Vault)和类似的东西，如果模块(const_set(:Vault, Module.new))还不存在，你可能必须创建它。
